Protective effect of zinc supplementation against copper toxicosis in sheep.
1. A study has been made of the effects of dietary zinc supplementation on the development of copper toxicosis in three groups each of eight 12-week-old lambs. 2. None of the lambs receiving 420 mg Zn/kg diet developed Cu toxicosis in the 24-week experimental period, compared with three in the control group receiving 43 mg Zn/kg and possibly one in the group receiving 220 mg Zn/kg. 3. Liver Cu ...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Sub-lethal effects of a copper sulfate fungicide on development and reproduction in three coccinellid species.
Copper-based fungicides reliably control various foliar diseases in citrus production, although they are suspected to exacerbate mite problems through various mechanisms. Studies have shown negative effects of various copper formulations on entomopathogenic fungi, nematodes, and parasitoids, but few have sought to measure its impact on the biology of predatory insects. We exposed the larvae of ...
متن کاملChronic Copper Poisoning in Sheep: Liver Injury
Pathogenesis of liver injury in chronic copper poisoning of sheep was investigated using two experiments. Test sheep were dosed orally with a 0.2 % solution of CuSO4.5H2O at the rate of 10 ml/Kg body weight on five days of the week, until first day of the haemolytic crisis (HC). Liver samples were taken during the prehaemolytic period and on the first or second day of the HC, liver changes were...
متن کاملUse of 64copper measurements to diagnose canine copper toxicosis.
Inherited canine copper toxicosis is a serious problem in Bedlington terriers and West Highland White terriers, and may also be a problem in other less-studied breeds. Affected dogs become ill at midlife with progressive and ultimately fatal liver disease. Treatments for removal of copper and prevention of copper accumulation are available, but are most effective if begun before the dog becomes...
